The output of your PC, via Ethernet, goes to the Raspberry Pi , which uses the Pi2AES to reclock and generate clean digital streams from the bits, that came over the Ethernet port.
It uses your PC and the Pi, this way, to feed your DAC this rather nice stream, rather than the much noisier USB stream which the DAC has to deal with normally.
You can if you want just hook a USB drive to the Pi and eliminate the PC entirely, but you will need a different OS on the Pi to handle that kind of setup.
